A. B. C. D.C.
Fault tolerance allows a system to continue functioning, even with degraded performance, if portions of it fail or degrade, without the entire system or service being taken down.
It can detect problems within a service and invoke compensating systems or functions to keep functionality going.
Although redundancy is similar to fault tolerance, it is more focused on having additional copies of systems available, either active or passive, that can take up services if one system goes down.
Elasticity pertains to the ability of a system to resize to meet demands, but it is not focused on system failures.
Automation, and its role in maintaining large systems with minimal intervention, is not directly related to fault tolerance.
The concept that pertains to the ability to detect problems within a system, environment, or application and programmatically invoke redundant systems or processes for mitigation is "Fault tolerance."
Fault tolerance refers to a system's ability to continue functioning even when there are failures or malfunctions in the system's components. It is an essential aspect of modern web service systems, which are designed to provide high availability and resiliency.
In fault-tolerant systems, redundant components are deployed to ensure that the system can continue to function even when one or more components fail. When a failure is detected, the system automatically switches to the redundant component without interrupting the service.
The fault tolerance concept goes beyond redundancy, which simply provides extra components to replace failed ones. Fault tolerance is about the system's ability to detect and respond to failures automatically without the need for human intervention. This is where automation comes into play, as it enables the system to detect failures and automatically invoke redundant systems or processes for mitigation.
Elasticity, on the other hand, refers to a system's ability to dynamically scale resources up or down in response to changing demand. While elasticity is important for ensuring that the system can handle sudden increases in traffic or workload, it is not directly related to fault tolerance.
In summary, fault tolerance is the concept that pertains to the ability to detect problems within a system, environment, or application and programmatically invoke redundant systems or processes for mitigation. It is an essential aspect of modern web service systems, which are designed for high availability and resiliency.
